While the tolls will disappear overnight on December 17, 2018, Highways England will not start paying people back for any TAG devices and accounts until January 2, 2018.

The deadline to apply for the closure of TAG accounts and to process refunds is March 31, 2019.

Every motorist will be entitled to a full refund of their outstanding TAG account balance as well as the £30 TAG device deposit. They must contact Highways England to authorise the closure of their account.

You will need to provide your TAG account number, a contact phone number, authorisation to refund, and your bank account number and sort code.

Highways England wants people to drop off their TAG devices at special collection points at Motorway Service Areas, shopping centres and retail parks. Alternatively, they can be posted back to the company at the Toll Administration Building.

Roadworks

Highways England said that on December 14, it would begin work on the Prince of Wales Bridge to create temporary lanes because the existing lanes would be too narrow for cars to drive through in their existing format.

Instead, temporary lanes will be created for drivers to use until the plazas are removed, and a speed restriction will be in place.

The toll plazas on each lane for drivers will eventually be removed, but doing so will take "significant work" to make a free-flowing three lane motorway.

Once the tolls have been stopped on the Prince of Wales Bridge on December 17, the M48 Severn Bridge will close for two days to allow similar new lane arrangements to be put in place.
